IMPROVEMENT CARRIAGE-SEATS.

" The Schedule referred to in these Letters Potent and making part ofthe same.

To alt whom it may concern.- Be it' known that I, GILBERT L. Honsox, ofR0- meo, in the county of Maconib, and in the State of Michigan, haveinvented certain new and useful Improvements in Seats for Carriages,Oars, &c.; and do hereby declare that the following is a full, clear,and exact descriptionv thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

The nature of my invention consists in the construction and arrangementof a spring-back for seats on vehicles of any description,railroad-cars, 860.

In order to enable others skilled in the art to which my inventionappertains, to make and use the same, I

will now proceed to describe its construction and op- .eration,referring to the annexed drawings, in which- 7 Figure 1 is a front viewof a carriage-seat with my improvement attached, and

Figure 2 is a view of one of the springs.

A represents a seat for a vehicle, made in any of the At the ends of theback 0, the springs D D are rounded, and placed in round journal-boxes,b b, so that the outer ends of the springs may be slightly turned ortwisted in the same.

Outside of the boxes I) b, the springs D D are turned down in acrank-form. i

The cranks (Z d, of the springs D D, are, by means of pivoted arm-piecesE E, connected with the irons 1* F, at the front of the seat A, in anyordinary manner.

It will be seen, that by pressing on the back 0, the arm-pieces E E andcranks d (1 cause the springs to twist, so that the back will yield,'butas soon as the pressure is removed from the back 0, the springs and backwillst once resume their natural position.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let- Witnesses:

G. F, MALLARY, 0. It. GREENE.
